Specification of Letters Patent.

Patented J one t, 1915.

Application filed October 6, 1911. Serial'No. 653,117.

T all whom it may concern:

Be it known that I, ARTHUR BATES, a. subject of the King of Great Britain, residing at Leicester, Leicestershire, England, have invented certain Improvements in Machines for U se in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like arts in the several figures.

be present invention relates to improve ments in machines intended primarily for closing the channels and molding or bendsoles of boots. or shoes and in this respect the in:- vention is in the nature of an improvement upon the machine which is described and illustrated in Letters Patent of the United States No. 1,019,085, dated March 5, 1912, issued upon a co-pending application filed by John Pennell Pride and the present applicant jointly. As in said prior machine, a machine embodying the present invention may al o be provided with means for pounding the upper of the shoe adjacent the feather or upper face of the margin of the sole, the latter term being used in its generic sense to include not only the sole of the usual Mc- Kay. pegged or nailed shoe but also a double or tapped sole as well as the combined welt and outsole of a welt shoe. Preferably also means is provided for pounding the edge of the sole. thereby both assisting in the closing of the channel and improving the finish of the sole edge.

principal object of the present invention is to simplify the construction and im' prove the operation of machines of the class described and with this object in view, a feature of the present invention comprises the provision of a work feeding wheel and a cooperating roll constructed and arranged to engage opposite s des of the margin of the sole together with mechanism for rotat ins: both wheel androll in the same direction. the relative speed of the roll being substantially. and preferably many times, greater than that of the-wheel. \Vith such a cohstruetion the sole engaging toolsbeing of suitable shape for the purpose will act not only to bend or mold the sole margin at a particular point but will also feed the shoe along so that the desired length of the sole margin will be progressively molded. At the same time, the roll, which in the illustrated embodiment of the invention is provided with spiral ribs, acts to close the channel by laying or pressing down the channel flap. Preferably the wheel and roll are frusto-conical in shape and are arranged on substantially horizontal axes with their bases oppositely directed so that during the operation of the machine the shoe may remain in substantially normal or upright po sition with the tread face of the sole resting upon and supported by the roll.

By providing. in addition to the tools which act upon the sole margin, a vibrating pounding tool acting upon the upper in the crease, often termed the welt crease, between the upper and the feather of the sole, the machine acts to' open. up the welt or to give the shoe a relatively wide edge as distinguished from a close edge. That is to. say, the hpper is pressed back from the edge of the sole at the same time that the sole margin is bent away from the upper so that the edge of the sole will appear to ex tend a relatively great distance beyond the upper, which is often desired in certain classes of shoes, such as heavy McKay shoes.

These and other features of the invention will now be described in detail in connection with the accompanying drawings whioh illustrate a preferred embodiment of the in' vention but it is to be understood that the invention may be embodied also in other specific forms without departing from the substance and scope of the invention as rlefined in the appended claims.

In the drawings: Figure l is a side elevation, partly in section. of the nmchine: Fin. 2 is a. plan with a portion of the casing or machine frame and certain other parts cut away to show the parts beneath; and Fig. 3 is a detail view of the edge beating tool and its actuating mechanism.

As illustrated, the machine comprises a base 2 having a vertically adjustable head 4 frame 16, bifurcated at its rear in the rear part of which is journaled transversely a driving shaft (5 and in the upper part of which is journaled longitudinally a sleeve 8 carrying at its front end a frustoconical feed wheel 10, the sleeve being rotated from the driving shaft by means of a worm 12 and worm wheel 14. A swinging end and pivoted upon the shaft 6 provides bearings for a shaft 18 which is driven from the shaft 6 by bevel gears 20, 22. This shaft 18 at its front end has a frusto-conical roll 24 which is spirally ribbed to adapt it to close the channel since it is driven at a relatively high peripheral speed as compared with the eripheral speed of the feed wheel and with the rate at which the shoe is fed. The active elements of Wheel 10 and roll 21 are substantially parallel but since the tread face of the shoe is slightly'rockered, or convex, intransverse section, the margin of the sole being operated upon is molded or bent away from the adjacent portion of the upper, thus opening up the crease between the upper and sole, as above explained.

Upon the frame 16 near the roll 24 is pivoted on a short shaft 26 a vertically extending lever 28 which carries at its u per end a vibrating edge beating tool 30 aving lateral ears 3? adapted to project under the sole. The tool 30 serves also as an edge gage and assists in maintainin the sole in proper cooperatire relationship with the tools which act upon it. The shank of tool 30 maybe adjusted in a socket in lever 28 and clamped by a bolt 34 Pivoted like wise on shaft 26 but at one side of lever 28, as shown in Figs. 2 and 3, is another lever 36 having a log 38 at its rear side in a socket of which is mounted a spring pressed pin 40 which bears against an abutment 41 upon lever 28. \Vith this construction, motion imparted to lever 36 is transmitted yieldingly to lever 28 so that the tool 30 strikes a yielding blow upon the edge of the sole and thus acts not only to solidify the edge but also, by reason of its tendency to upset the edge, assists the other tools in the closing of the channel. The mechanism for 05-- cillating lever 36 comprises a rod 42 screwed into a pivoted blockAZl at the lower end of lever 36, the other end of this rod being similarly connected to the lower end of a cam lever 4-1 which is pivoted to the machine frame at 4.) and which carries a cam roll 46 that engages a face cam 48 on the driving shaft 6.

The machine is preferably provided also with an upper pounding tool 54 which is located within and concentric with the feed wheel 10, its end projecting slightly beyond the end of thewheel. This pounding tool is attached to a spindle 56. which slides in the sleeve 8 and projects beyond it at the rear of the machine. The end of this spindle enters a recess 58 in a boss (30 at the upper end of the cam lnwer ll, above 1nentioned, and abuts against the end of a pin or screw 62 adjustably secured in the boss. To reduce wear the ends of the pin and of the spindle may be case-hardened. To pe mit some play between the spindle M3 and the cam lever ii but to prevent the entire withdrawal of the spindle from the recess, the boss 60 is provided with a transverse hole 64 which receives a transverse pin 66 of smaller diameter extending through the spindle.

The front end of frame 16 :indthe roll 26 are normally supported in operative position by means of a plunger 70 movable vertically in a recess 72 in the head of the machine and hearing at its upper end against the frame 16. The plunger is pressed upwardly by a spring 7-11, the lower end of which is supported by a hollow adjustable screw plug 76 but may be depressed by a suitable treadle (not shown) in a wellknown manner in order that the work may be inserted between the. feed wheel and the channel closing roll. Adjustable or other stops 78, 80 upon the machine frame 4 and the swinging frame 16, respectively, limit 'the relative approach of roll and wheel.

It will be noted that the channel closing roll 24 and the edge beating tool 30, being upon the same frame, always maintain the same relationship notwithstanding variations in the thiclniess of the work.

If any portion of the extreme edge of the sole is very badly deformed or recessed away from the tread face, the lower surface of roll 24 may be used preliminarily to pound and reshape the sole edge. For this reason, a guard or rest 82 hung on pivot Shaft 26 may be provided. The pressure of the work against the tools 30, 54 may be relied upon to keep the cam roll 46 in operative relation to its cam or if desired a suitable spring acting upon lever 44- may be employed for the purpose.

The operation of the machine in opening the crease,'bending the sole margin and closing the channel will be readily understood frcin the foregoing description. As indicated in Fig. 1, the shoe will be held by the operator in an upright position with its sole nearly horizontal. As the shoe is pressed inward against the pounding tools 30 and 54, while the margin of the sole is gripped between the feed wheel 10 and the ribbed roll 24, not only will the channel be closed by the wiping action of the ribbed roll 24 but th nmrgin of the sole will also be bent away from the upper and the upper will be conformed to the last if, as indicated, the last is in the shoe.
